Patented Apr. 8, 1930 CHARLES A. WOOD, OF CLAY CENTER, KANSAS TOY AXLESTAMPING AND curtains MACHINE Application filed April 10,

My invention relates to a shearing and stamping machine for use in themanufacture of axles for wheeled toys.

The object of my invention is to provide a combined stamp and shear tobe used in the fabrication of axles for wheeled toys.

Another object of my invention is to provide a mechanism that will inone operation trim and flatten a wire nail or similar piece of metal foruse as an axle in wheeled toys.

A still further object of my invention is to provide a mechanism of thekind described actuated by a lever and having cams for the propulsionand retraction of the stamping and cutting elements.

A still further object of my invention is to provide a mechanism of thekind described in which the stamping and shearing elements are actuatedby the cam action of a lever and the cam action is timed to propel thestamping and shearing elements to flatten and trim the axle in oneoperation.

These and other objects will hereinafter'be more fully explained.

Referring to the drawings:

Fig. 1 is an elevation of the working parts of the machine with one ofthe side plates removed and the cap screws and pin in cross section andthe jaws in the open position.

Fig. 2 is a fragmentary longitudinal section of the machine with theworking parts in the position shown in Fig. 1.

Fig. 3 is a fragmentary elevation of the machine taken in an oppositeview from that shown in Fig. 1 illustrating the closed position of thejaws with parts removed for the purpose of illustration.

Fig. 4 illustrates a toy automobile with its axle held in positionpreparatory to the 4.0 stamping and trimming operation with regard tothe jaws of the machine.

5 illustrates the completion of the operation of stamping and trimmingthe axle.

Fig. 6 is a fragmentary View of a portion of a toy automobile and onewheel illustrating the formation of the end of the axle after thestamping and cutting operation.

A lever 1 is rigidly connected to a member so by the bolts 3 and 1 whichalso position 1929. Serial No. 354,085.

the retracting arms 5 and 6. A cam member 7 is fitted on the lowerextremity of the lever 1 and adjacent to the member 2 as shown. Thelower extremity .of the member 2 is formed as a-cam in the mannerillustrated. Let A designate the surface of the cam portion on themember 2 and B designate the surface of the cam portion on the member 7,the member 7 and the member 2 participate in movement and are trunnionedby the pin 8 on carried in the side plates 9 and 10.

The side plates 9 and 10 are rigidly connected by means of rivets or capscrews and spaced by the frame portions 11, 12, and 13, the frameportion 13 being rigidly fastened C to the base member 14 by the capscrews 15 and 16. The frame portions 11 and 12 act as guides for themovable jaws 1'? and 18 which are slidably positioned between the sides9 and 10 and the said guides. The pins 5 17 and 18 threadedly engage themovable jaws 17 and 18 respectively in a rigid manner and extend throughthe slots 19 and 20 in the side plates 9 and 10 respectively and engagein the arcuated cuts 21 and 22 in the retracting arms 6 and 5respectively.

The stationary jaw 23 is positioned upon the shims 2 1 and 25, whichrest upon the member 13, and against the spacer 27. The cap screw 26 andthe plate 26' position the shims and jaw 23 as shown. The cap screw 28extending through the slot 29 in the side plate 9 and the slot 30 in thespacer 27 threadedly engages the stationary jaw 23 and holds the jawrigidly in place.

The upper extremity of the jaw 17 slidably engages the cam surface A andthe. up per extremity of the jaw 18 slidably engages the cam surface B.lVhen the lever arm is rocked in the direction shown by the arrow s inFig. 1, by means of the handle 31, the cam surfaces A and B propel thejaws 17 and 18 respectively to the positions illustrated in Fig. 3. j 1i V The lower extremity of thejaw 17 is placed 93 approximately againstthe upper surface of the stationary jaw 23 by reason of the cam surfaceA engaging with the upper extremity of the jaw and the jaw 18 passes theedge G of the stationary jaw 23 in the manner shown at D by reason ofthe engagement of its upper extremity with the cam surface B. The slots21 and 22 in the retracting arms 6 and respectively function only toretract the jaws 17 and 18 into the position shown in Figs. 1 and 2after the completion of the operation shown in Fig. 3. The slots aredesigned to allow free downward movement of the jaws and are notexpected to transmit any force in the stamping and trimming operation.

An example of the work performed by this machine is illustrated in Figs.4, 5, and 6. Fig. 4 illustrates the jaws in the open position. A toyautomobile 32 having wheels 33 and a Wire nail or similar rod member 34,to trunnion the wheels, is placed in the position shown in Fig. l withrespect to the aws. The end of the nail at E is positioned between the20 jaws at the beginning of the operation. Fig.

5 illustrates the completion of the operation,

the jaw 17 has pressed the nail against the jaw 23 and the aw 18 hassevered the portion E, leaving the end of the nail or axle in the 5shape illustrated at F in Fig. 6. In this manner the nail 3% now holdsthe wheels 33 rotatable on the toy 32 and the wheel 33 adjacent theportion F of the axle cannot pass over this flattened end. By the use ofthis mechanism the end of the axle is flattened and trimmed in oneoperation. I have found that this saves considerable time and expense inthe manufacture and assembly of wheeled toys.

35 Such modifications may be used as come within the scope of theappended claim and what I do claim as new and desire to se cure byLetters Patent is:

In a mechanism for forming axles for wheeled toys, to trim and flattenthe end of the axle, a stamping element comprising two jaws, onestationary and one movable and the movable jaw being separately slidablefrom the stationary jaw and being pro- 4 polled toward the stationaryjaw by a cam surface on a lever and being retracted from the stationaryjaw by reason of a laterally extending pin engaging in an arcuated slotin an arm connected to the lever, and a shear- 5 ing member propelledpast the edge of the stationary jaw in the manner of a cutter and thepropulsion of the shearing member being actuated by another cam surfaceon the lever and being retracted by reason of a laterally extending pinengaging in an arcuated slot in an arm afiixed to the lever and theactuating cam mechanism timed to propel the flattening and shearingmembers in the same movement of the lever.

In testimony whereof I afiix my signature.

CHARLES A. WVOOD.
